资源简介

摘要: 山体滑坡是最常见的地质灾害之一,快速准确地获取滑坡的危害程度和分布情况对灾后救援具有重要意义。通过引入形态学开运算和区域水平集算法来构建面向对象的滑坡提取方法,以高分二号卫星的多光谱影像为数据源,在位于尼泊尔巴格马蒂专区的研究区中,分别运用构建的方法和基于像元的滑坡提取方法进行滑坡提取实验,并对两种方法的滑坡提取结果进行精度分析。实验结果表明:面向对象的滑坡提取方法总体上比基于像元的滑坡提取方法的提取结果精度更高,对云层和积雪的抗干扰能力更强。  关键词: 滑坡提取;  多尺度分割;  水平集演化;  形态学方法     Abstract: Landslide is one of the most common geological disasters,and it is of great significance to quickly and accurately obtain the hazard degree and distribution of landslide.By introducing the morphological opening operation and the regional level set algorithm to construct the object\|oriented landslide extraction method,and using the multi\|spectral image of GF\|2 satellite as the data source,the landslide extraction experiment is carried out by using the constructed method and the landslide extraction method based on the pixel in the study area of the Bagmati area in Nepal,and the results of the landslide extraction are analyzed.The experimental results show that the object\|oriented landslide extraction method is more accurate than the extraction method based on the pixel,and the anti\|interference ability of the clouds and snows is stronger than that of the pixel\|based landslide extraction method.
